Almost 50 endangered sea turtles have arrived at Gulf World Marine Institute in Panama City Beach.

Officials say the turtles were found stranded in shallow bay waters due to frigid temperatures over the past few days.

The News Herald of Panama City (http://bit.ly/1cU4ZVK ) reports the turtles went into a hypothermic state and became very weak because of the cold weather. Many now have developed a secondary illness.

Officials from Gulf World, the Florida Fish and Wildlife Conservation Commission, the Gulf Island National Seashore and University of Florida volunteers have found the turtles and brought them to the marine center for rehabilitation.

Gulf World officials say the turtles are in intensive care. Their body temperatures will be slowly warmed and they'll receive any necessary medicine.
